For the boiler-turbine unit in power systems, a coordinated control structure plays crucial role maintaining balance supply and demand of energy, reducing pollutant emissions optimizing energy efficiency. The matching requirements turbine boiler, wide range load changes, cooperative operation many devices system pose challenges to designing for boiler system, thus making design difficult task. ...

Property-oriented testing uses the specification of a property to drive the testing process. The aim is to validate a program with respect to a target property, that is, to exercise the program and observe whether the property is violated or not. We define a test strategy for safety properties in cyclic control systems. It consists of the stepwise construction of test scenarios. Each step explo...

Main essence for the thermal power plants that may be either coal or natural gas power plants to be in command of the temperature and pressure controllers (PI.PD, PID) is generally employed. The raw material, coal is nosh in to the boiler using conveyer system and it is a time shifting one. This coordinated boiler turbine system, multivariable complex process, nonlinear and also slowly time var...

Superheater is for generating superheated steam from the saturated steam from the evaporator outlet. In the case of pulverized coal fired boiler, a relatively small amount of ash causes problems with ash fouling on the heating surfaces, including the superheaters. In the convection pass of the boiler, the flue gas temperature is lower and ash deposits can be loose or sintered. Ash fouling not o...

Abstract Accurate predictions of energy efficiency facilitate the energy-saving renovation industrial boilers. To improve prediction accuracy, this paper proposes an boiler model based on stacking ensemble learning method. The base models, including LR, RF, GBDT, XGBoost, and ANN, are established in study, then method is employed to integrate these models into a strong model. Experimental resul...

Amit Kumar Jain Abstract— Presently the world has enormous advancement in science and technology the topic considered here is just a drop out of an ocean of knowledge. Higher product quality, better reliability, better availability of plants, optimization of cost and efficient working of boilers is the chief concern now a days. Generally the production can be increased by the efficient use of b...

AbstractDeaerator is normally used in Chemical Industries, Process Industries, Power Plants and in Paper and Pulp Industries. The oxygen in the boiler feed water is the main reason of boiler corrosion. Oxygen corrosion is one of the biggest dangers of boiler. The function of the deaerator is to remove the dissolved oxygen from the boiler feed water before entering into boiler .The removal of di...
